Lean Six Sigma Green Belt
Do you have improvement ideas that never turn into lasting results? Learn to lead improvement projects that actually deliver, with documented savings averaging NOK 2.5 million per project (source: GLSS).
Format: 3 classroom days, 2 online meetings (1.5 h each) & e-learning (~2 h).
Next course: 19 May, 2–4 June (Ersgard, Stjørdal) & 11 June.
Who is this for?
This course is for you if you:
- Need to lead improvement projects and want a structured method that actually delivers results.
- Are responsible for improving operational performance, and want tools to do it systematically.
- Are tired of starting improvement projects that fade out because no one follows through.
- Want to prove root causes with data, not just guess and hope the solution holds.
- Work with quality, environment, sustainability, or process improvement and need documented methods.
"Focus on the things that actually matter - the process, the thinking, the questions - not the abbreviations and the diagrams."

Certificate & diploma
What will you get out of this?
- Lead improvement projects from start to finish using a structured, proven method.
- Choose the right project from the start, so you solve problems that actually matter to the bottom line.
- Prove root causes with data and analysis, not gut feeling, and implement solutions that actually hold.
- Ensure lasting results and transfer learning to the rest of your organisation.
- Course diploma after completing the classroom days. Green Belt certificate when you also complete and have an improvement project approved. (read more under "Course content")
Green Belt projects generate average savings of approximately NOK 2.5 million per project (source: GoLeanSixSigma).
What participants say
"An interesting and engaging course that applies to process improvement in any industry. An enthusiastic and knowledgeable instructor who clearly has a passion for the subject. Made it easy to stay focused, even at the end of a long day."
Jarle Gjendem Olsen, Green Belt course
"The tools for improving processes and reducing errors have been very useful. The use of process mapping to understand variation was particularly valuable."
Nina Lareng, Green Belt course
"Your Lean Six Sigma workshops were exceptionally effective, offering actionable insights that drove immediate improvements. I highly recommend Lean Tech for your professionalism and expertise."

How the course works
- E-learning (~2 hours, 1-year access): You start with the e-learning module before online meeting 1. It covers the foundation you need to identify and prioritise the right improvement project.
- Online meeting 1 (1.5 hours): We help you find and define an improvement project in your own organisation, so you arrive at the classroom days with a concrete project ready to work on.
- 3 classroom days: You learn the methods and tools for leading improvement projects from start to finish. You practise through a Lego simulation and work on tasks connected to your own project.
- Online meeting 2 (1.5 hours): A few weeks after the classroom days, we meet again. By then you have had time to digest the content and start thinking about how to apply it. We go through your questions and help you move forward with your project.
Key topics
Leading improvement projects with DMAIC
The course teaches you to lead successful improvement projects. We focus on what actually matters in practice:
- How to write a good problem description and set the right focus?
- How to make a problem measurable and set specific goals?
- How to describe and document project benefits?
- How to use data and process maps to understand root causes?
- How to separate signal from noise and respond correctly?
- How to visualise and prove cause-and-effect relationships?
- How to prioritise and choose solutions that last?
- How to ensure lasting improvement and transfer learning to others?

Do I need prior knowledge of Lean or Six Sigma?
No. The course starts with the e-learning module, which gives you everything you need to get started. If you have completed the Yellow Belt or have experience with improvement work, you will recognise much of the content and be able to go deeper faster.
How much time do I need to set aside?
The e-learning takes approximately 2 hours and is completed at your own pace. Each online meeting is 1.5 hours, and the classroom programme is three full days. On top of that comes the time you invest in working on your own project. Those who put in the work consistently get the best results.
What kind of project should I choose?
Choose a problem that matters to your team or organisation and is realistic to work on over 12 months. It could be anything from long lead times and high scrap rates to inconsistent quality or inefficient processes. You will get guidance on project selection in online meeting 1.
What is included in the price?
E-learning with 1-year access, 2 online meetings, 3 classroom days including lunch and refreshments, course materials, project templates, and a course diploma. Coaching for certification is purchased separately.
What is the difference between Yellow Belt and Green Belt?
Yellow Belt teaches you to solve problems at the root cause in your own day-to-day work. Green Belt goes further: you learn to lead improvement projects, work with data and statistics, and document savings in the millions. Green Belt is recommended if leading improvement work is part of your role.
I have tried to improve processes before. Why will this be different?
Because most improvement efforts fail by attacking symptoms, not root causes. The DMAIC methodology gives you a structured approach to finding, proving, and solving what is actually driving the problem, along with tools to make sure the solution holds over time.
What is the FAST method, and how does it differ from DMAIC?
FAST stands for Focus, Analyse, Solve, Track and is our pedagogical approach to DMAIC (Define, Measure, Analyze, Improve, Control). FAST simplifies DMAIC into four phases that are easier to remember and apply in practice:
- Focus (Define + Measure): Choose the right problem, measure the current situation, and set clear goals.
- Analyse (Analyze): Separate signal from noise, understand the process, and prove root causes.
- Solve (Improve): Fix root causes, not symptoms.
- Track (Control): Ensure lasting results by monitoring over time.
You learn the same methodology as traditional DMAIC, but with a structure that is easier to remember and apply when leading improvement projects in your own organisation.
Can I use this even if I am not a manager?
Yes. Many participants are engineers, specialists, and project team members without people management responsibilities. What you need is access to a real problem and the opportunity to work on it over time.
Does this work for my industry?
DMAIC works regardless of industry because the method is about processes, not products. We have had participants from manufacturing, healthcare, construction, the public sector, and more. The project you choose comes from your own working environment.
